Based on current theories of multimedia learning, we propose a strategy for learning from animations. Two different experimental studies were conducted in order to evaluate the strategy. In the first study, 22 sixth graders learned from an animation without the strategy while 21 students were encouraged to make use of the proposed strategy during learning; use of the strategy was not monitored. The students who were encouraged to take advantage of the strategy learned significantly more than the students who were not asked to do so. In the second study, three groups of sixth graders were investigated. The first group consisted of 49 students who learned from an animation without the strategy. The second group consisted of 52 students who were encouraged to make use of the strategy during learning; but use of the strategy was not monitored. The third group consisted of 53 students who were also encouraged to make use of the strategy during learning and their use of the strategy was monitored. The results of the second study replicated the findings of the first study. Furthermore, learning was most successful when the students' use of the learning strategy was monitored. 相似文献

Argumentation skills play a crucial role in science education and in preparing school students to act as informed citizens. While processing conflicting scientific positions regarding topics such as sustainable development in the domain of ecology, argumentation skills such as evaluating arguments or supporting theories with evidence are beneficial for developing deep understanding and well-grounded conclusions. We developed a 50-min training intervention to foster argumentation skills in the domain of ecology on topics related to sustainable development and analyzed its effects in a control-group design: (a) training intervention to foster argumentation skills (n = 41), (b) no such training intervention (n = 42). Results showed that this short-term training intervention successfully fostered three components of argumentation skills (i.e., evaluative knowledge, generative knowledge, and argument quality) and declarative knowledge about argumentation. The positive effect on declarative knowledge was stable 1 week after the training and it was mediated by learning processes during the training intervention: self-explaining the principles of argumentation underlying the video-based examples mediated the effect on declarative knowledge 1 week after the training. In short, the training intervention is an effective instructional method to enhance argumentation skills as well as declarative knowledge about argumentation. 相似文献

Providing prompts to induce focused processing of the central contents of instructional explanations is a promising instructional means to support novice learners in learning from instructional explanations. However, within research on the expertise reversal effect it has been shown that instructional means that are beneficial for novices can be detrimental for learners with more expertise if the instructional means provide guidance that overlaps with the internal guidance provided by the prior knowledge of learners with more expertise. Under such circumstances, prompts to induce focused processing might even be detrimental for learners with expertise whose prior knowledge already provides internal guidance to learn from explanations. On this basis, we aimed at experimentally varying expertise by developing prior knowledge. Specifically, we used a preparation intervention with contrasting cases to enhance learners’ prior knowledge (expertise). Against this background, we tested 71 university students in a 2 × 2 factorial experimental design: (a) Factor of expertise. Working with contrasting cases to develop prior knowledge and expertise to provide internal guidance to learn from instructional explanations (with vs. without), (b) Factor of prompts. Prompts to induce focused processing of the explanations (with vs. without). The results showed that prompts to induce focused processing fostered conceptual knowledge for novice learners whereas prompts hindered the acquisition of conceptual knowledge for learners with expertise that was developed by working with contrasting cases beforehand. Moreover, measures of subjective cognitive load and learning processes suggest that the instructional guidance provided by prompts compensated for the low internal guidance of novice learners and overlapped with the internal guidance of learners with expertise. 相似文献

Academics are increasingly expected to produce concrete and directly applicable solutions to hard-to-solve ‘real-world problems’ such as poverty, development, and environmental degradation. However, conventional assessments of the impact of science on society have not yet been adequately adapted to capture the diverse effects of this type of problem-centred research. Drawing on a case study of a large-scale project on (un)sustainable consumption, this paper demonstrates the range, complexity and potential long-term nature of impact in interdisciplinary sustainability research. It thus supports arguments for alternative approaches to impact assessment that question conventional views of translating scientific knowledge into action, value the multi-directionality of science-society relations and recognise diverse forms of engagement between scientists and non-scientific actors through non-academic channels and outputs. The paper also challenges common (mis)conceptions of work practices in a university context by demonstrating the highly innovative and inclusive nature of much sustainability research that seeks to address the needs of diverse communities of actors. It is argued that only radically different ways of conceptualising and measuring short-, medium- and long-term impacts can capture the success or otherwise of social-scientific and interdisciplinary sustainability research. 相似文献

Relationships between skeletal maturation and fundamental motor skills and gross motor coordination were evaluated in 429 children (213 boys and 216 girls) 7–10 years. Skeletal age was assessed (Tanner-Whitehouse 2 method), and stature, body mass, motor coordination (Körperkoordinations Test für Kinder, KTK) and fundamental motor skills (Test of Gross Motor Development, TGMD-2) were measured. Relationships among chronological age, skeletal age (expressed as the standardised residual of skeletal age on chronological age) and body size and fundamental motor skills and motor coordination were analysed with hierarchical multiple regression. Standardised residual of skeletal age on chronological age interacting with stature and body mass explained a maximum of 7.0% of the variance in fundamental motor skills and motor coordination over that attributed to body size per se. Standardised residual of skeletal age on chronological age alone accounted for a maximum of 9.0% of variance in fundamental motor skills, and motor coordination over that attributed to body size per se and interactions between standardised residual of skeletal age on chronological age and body size. In conclusion, skeletal age alone or interacting with body size has a negligible influence on fundamental motor skills and motor coordination in children 7–10 years. 相似文献

Abstract This study describes the development and the evaluation of quality assurance criteria for online dental education. These criteria were developed by the authors and evaluated by oral health professionals through an Internet survey. The survey indicated that oral health professionals ranked the creation of scientifically based, frequently updated courses that clearly define their educational goals and objectives as highly important. 相似文献

Argumentative thinking requires not only the skill to apply argumentative strategies such as supporting theories with evidence but also the will to apply these strategies by considering argumentative thinking to be both reasonable and worthwhile. Focusing on direct instruction for the initial acquisition of both skill and will, we developed a new short-term computer-based training intervention. We tested its effects on learning processes and learning outcomes in an experimental study with 147 German high school students. Our intervention fostered facets of both skill (i.e. a declarative knowledge about argumentation) and will (i.e., epistemic orientation, intellectual values, and epistemic knowledge). We gained additional insights into learning mechanisms, such as the mediating effects of the learners' self-explanation activities and the advantage of addressing will before skill. 相似文献
